Interior wall latex paint is one of the most popular decorative materials for home decoration. It has many advantages such as convenient construction, strong hiding power, rich color, scrub resistance, etc. The color is well matched and the quality is guaranteed, which can provide a warm home. Environment, but in actual construction, some problems are likely to cause trouble to customers. Let's talk about how to control the problem during construction.
First, the brush is mainly brushed with a wool brush and a pen. The advantage is that the brush marks are even, the disadvantage is that it is easy to lose hair, and the efficiency is low;
Second, roll coating, this method saves material, but the brushing in the corner area is not in place, and it is easy to produce rolling marks, affecting the appearance; Third, spraying, divided into air spraying and airless spraying, mainly The spraying machine is used to complete the construction. The advantage is that the construction efficiency is high and the paint film is smooth. The disadvantage is that the atomization is serious and the materials are wasteful;
Common problems in construction
First, the wall cracking: this phenomenon is the most common, the specific reasons must be determined according to the situation, if it is the GRC lightweight partition wall, then the joint should be carefully cracked, generally with glass cloth or kraft paper, partition board The characteristics of the product are prone to small cracks, so in the home decoration to ensure that there is little cracking phenomenon, it is best to paste the glass cloth or bean cloth. If it is a load-bearing wall or a solid wall, the cracking may be due to the construction of the putty is too thick or the interval is short and the putty is not Dry, in this case, the old house was transformed into a leveling situation.
Second, the wall flowers, uneven color: mainly the base layer color is not the same, no treatment, this situation must be covered by full putty or brush once primer. In addition, when purchasing materials, pay attention to picking the same manufacturer, the same product and the same batch number, otherwise there will be color difference.
Third, the surface is rough: the main reasons are that the base layer is not clean, the brush has sand, debris or the operating environment is not clean. Precautions are cleaned at the base, cleaned and cleaned.
Fourth, the skin: the main reason is that the base layer is too smooth or oily, preventive measures with a steel brush to brush the base layer and clean, oil stains with solvent to do decontamination treatment.
Correct construction method and attention
Before the construction of latex paint, all the shells and cracks on the wall should be removed, and the filler should be used to fill the wall. The wall surface is cut, the residual pulp, garbage and oil are removed. The large wall surface of the outer wall should be treated as a compartment. Sand the uneven surface and the rough surface, then rinse the wall surface and paint it when it is completely dry. Before using the roller, brush the area that the roller can't be applied with a brush. After 2~3 hours, roll it over with a large area. The drum should be made of a high quality roller. Primer should be applied first during construction, and the primer should be completely dry after about 6 hours. Avoid construction in rain and fog. Generally, the construction is best at a temperature of 25 ° C and a humidity of 50%. Paint must be protected from rain and dust during painting and before drying. Note that it is not advisable to work with wall gauge temperatures below 10 °C. In the second renovation, the original paint layer must be removed before the latex paint is painted. Then use a double fly powder and cooked powder to mix and mix. Then paint the latex paint, the surface layer should be painted 2 times to 3 times.
In terms of construction, the putty on the wall should be made up of special white powder, white cement, water, chemical paste, and 801 construction glue. When blending, first use a small amount of water to open the white cement, and then put the appropriate amount of 801 glue, chemical paste, old powder, and stir until the appropriate concentration. The quality requirements should be flat, the second should be light, and there should be no pores. The test method can use a light bulb to observe from the four corners of the wall, and the brush is flat and clear at a glance. After the putty is approved, it should be completely dry. Apply the wall primer with the latex paint and then apply the finish. Both the primer and the topcoat can be adjusted slightly to avoid leaving a brush mark. Every time the paint is allowed to dry out, it can be painted a second time. In addition, if there is paint construction at the same time, it should be finished after the old powder is approved, and then the paint is completely finished, and then the latex paint is applied to avoid the ointment caused by the toluene evaporating from the paint, causing unnecessary loss.
